Abstract

The changes in land use associated with urbanization and industrialization modify the microclimate, leading to the formation of urban heat islands, in which cities are warmer than the surrounding landscape. In this sense, this study seeks to analyze the pattern of land use and land cover and the Land Surface Temperature (TST), which was estimated from orbital images of Sensor TIRS, Landsat 8, on 2 dates in the summer and winter months of the year 2017, as well as seek indicators of the correlation between Surface Temperature and Air Temperature from 5 points of analysis on the study area, comprising the urban perimeter of the municipality of Ponte Nova-MG, in Zona da Mata Mineira, a city situated on a dissected plateau and a Tropical Climate of altitude. The results showed a strong correlation (73.0%) between TST and air temperature, considering the Pearson correlation. As it was also verified a very strong correlation in summer (98.0%) and strong in winter (82.0%) between NDVI and Air Surface Temperature.
